Begonia plant named &#39;tnbegrm&#39;

ABSTRACT

A new and distinct form of  Begonia  plant characterized leaves colored burgundy to silvered burgundy with olive green along veins, dark burgundy red leaf backs, medium pink flowers, a trailing habit, and excellent vigor.

Botanical denomination: Begonia hybrid.

Variety designation: ‘TNBEGRM’.

Parentage: Begonia hemsleyana hybrid unnamed×Begonia boliviensis hybrid unnamed.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia, of the family Begoniaceae, and given the cultivar name, ‘TNBEGRM’. This plant originated from a test cross with an unnamed Begonia boliviensis hybrid as the pollen parent. The new cultivar originated from a cross between Begonia hemsleyana unnamed hybrid (unpatented), as the seed parent and Begonia boliviensis hybrid unnamed (unpatented), as the pollen parent. There are no similar Begonia on the market known to the inventor. This selection is uniquely characterized by:

-   -   1. leaves colored burgundy to silvered burgundy with olive green         along veins,     -   2. dark burgundy red leaf backs,     -   3. medium pink flowers,     -   4. a trailing habit, and     -   5. excellent vigor.

Compared to the seed parent Begonia hemsleyana hybrid unnamed, an unpatented plant, the new cultivar has leaves a trailing rather than an upright, shrubby habit and dark simple leaves rather than green to silver palmately compound.

Compared to the pollen parent, Begonia boliviensis hybrid unnamed, an unpatented plant, the new cultivar is trailing rather than sprawling, with smaller flowers that are pink rather than red orange, and maroon leaves instead of green.

The new variety has been reproduced only by asexual propagation (leaf cuttings and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by micropropagation using the meristem as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new Begonia cultivar based on observations of 9-month-old specimens grown in one gallon containers in a warm greenhouse in June in Canby, Oreg. Canby is Zone 8 on the USDA Hardiness map. Temperatures range from a high of 95° F. in August to 32° F. in January. Normal rainfall in Canby is 42.8 inches per year. The color descriptions are all based on The Royal Horticultural Society Colour Chart, 5^(th) edition, 2007.
